Fallen arches, or flatfoot, is a condition in which the arch on the inside of the foot is flat and the entire sole of the foot rests on the ground. It affects about 40 percent of the general population. Although flat feet in and of themselves are not usually problematic, they can create problems in the feet, hips, ankles and knees. Pain may be experienced in the lower legs if there are alignment problems and if the individual is engaged in a lot of heavy, high-impact activities that put stress on the bones and muscles of the lower legs.

Causes

Flat feet in adults can arise from a variety of causes. Here are the most common. An abnormality that is present from birth, stretched or torn tendons, damage or inflammation of the posterior tibial tendon (PTT), which connects from your lower leg, along your ankle, to the middle of the arch, broken or dislocated bones. Some health conditions, such as rheumatoid arthritis, Nerve problems. Other factors that can increase your risk include obesity, diabetes, ageing and Pregnancy.

Symptoms

Knee/Hip/Back Pain - When the arch collapses in the foot, it triggers a series of compensations up the joint chain, leading to increased stress on the knee, pelvis and low back. Plantar fasciitis - This condition is characterized by heel pain, especially with the first few steps you take. The plantar fascia stretches as the arch falls, putting stress on the heel. Bunions - If you see a bony bump developing at the base of your big toe, you are likely developing a bunion. It may be swollen, red or painful when it rubs against your shoe. A flattened arch spreads the forefoot and causes the big toe to deviate toward the second toe. Shin splints - This term generally refers to pain anywhere along the shinbone. It is typically due to overuse and is aggravated after exercise and activity.

Diagnosis

Many medical professionals can diagnose a flat foot by examining the patient standing or just looking at them. On going up onto tip toe the deformity will correct when this is a flexible flat foot in a child with lax joints. Such correction is not seen in the adult with a rigid flat foot. An easy and traditional home diagnosis is the "wet footprint" test, performed by wetting the feet in water and then standing on a smooth, level surface such as smooth concrete or thin cardboard or heavy paper. Usually, the more the sole of the foot that makes contact (leaves a footprint), the flatter the foot. In more extreme cases, known as a kinked flatfoot, the entire inner edge of the footprint may actually bulge outward, where in a normal to high arch this part of the sole of the foot does not make contact with the ground at all.

Treatment in adults generally consists of wearing spacious, comfortable shoes with good arch support. Your doctor may recommend padding for the heel (heel cup) or orthotic shoe devices, which are molded pieces of rubber, leather, metal, plastic, or other synthetic material that are inserted into a shoe. They balance the foot in a neutral position and cushion the foot from excessive pounding. For children, treatment using corrective shoes or inserts is rarely needed, as the arch usually develops normally by age 5.

Surgery is rarely needed.

Surgical Treatment

Generally one of the following procedures is used to surgically repair a flat foot or fallen arch. Arthrodesis. One or more of your bones in the foot or ankle are fused together. Osteotomy. Correcting alignment by cutting and reshaping a bone. Excision. Removing a bone or a bone spur. Synovectomy. Cleaning the sheath that covers the tendon. Tendon transfer. Using a piece of one tendon to lengthen or replace another. Arthroereisis. placing a small device in the subtalar joint to limit motion. For most people, treatment is successful, regardless of the cause, although the cause does does play a major role in determining your prognosis. Some causes do not need treatment, while others require a surgical fix.
